TECHNOLOGICAL FIELD

An example embodiment of the present disclosure relates generally to themanufacture of a wing panel and, more particularly, to the automatedassembly of a wing skin planks to form a wing panel utilizing asequential series of manufacturing cells.

BACKGROUND

In order to manufacture a wing panel, a plurality of stringers and aside of body chord are loaded into a fixture to maintain their relativepositions. A plurality of wing skin planks are then positioned proximatethe stringers and the side of body chord. Once properly positioned, thewing skin planks are clamped to the fixture and thereafter tacked to thestringers and the side of body chord so as to define either an upperwing panel or a lower wing panel. The resulting wing panel is then movedvia a crane system to a riveting station that may employ, for example,one or more C-type Gemcor® riveting devices. The riveting devices theninstall rivets between the tack fasteners. For relatively large wingpanels, five to seven riveting devices may be required with a dedicatedoperator required to operate each of the riveting devices. The tackfasteners that were previously installed are then either drilled out andreplaced by traditional rivets at the riveting station or manuallyremoved and replaced by bolts while the wing panel is stationed in apanel pickup area. The upper and lower wing panels may then be assembledto produce the resulting wing box.

The manufacturing process for producing a wing panel and, in turn, forassembling the wing panels to form a wing box requires substantial humaninvolvement. As such, it may be challenging to increase the rate atwhich wing panels and, in turn, wing boxes are fabricated utilizing theconventional fabrication process.

DETAILED DESCRIPTION

Embodiments of the present disclosure now will be described more fullyhereinafter with reference to the accompanying drawings, in which some,but not all embodiments are shown. Indeed, these embodiments may beembodied in many different forms and should not be construed as limitedto the embodiments set forth herein; rather, these embodiments areprovided so that this disclosure will satisfy applicable legalrequirements. Like numbers refer to like elements throughout.

As shown in FIGS. 1 and 2, the system of one embodiment includes aplurality of sequential operational cells with different manufacturingoperations being performed within each cell. The cells are arranged insequence such that a workpiece moves from a first cell, such as astaging cell 20, to the last cell, such as a side of body cell 34, inorder to allow a wing panel to be fabricated. The upper and lower wingpanels may then be assembled to form a wing box. As described below thewing skin planks and the resulting wing panels are generally movedthrough the assembly process, such as from cell to cell, by an automatedmaterial transport system, such as an overhead positioning system. Othercomponents, such as stringers, may also be delivered to the variouscells upon carts that are automated so as to limit human involvement. Asillustrated in FIG. 2, the system may include two or more buffers 24, 30in which partially assembled workpieces are maintained, stored or thelike while awaiting entry into the next cell in the process. Byincluding one or more buffers, the operations performed by each cell mayoccur at slightly different rates without allowing the rate of operationof a subsequent cell to limit the rate of operation of a prior cell,while still permitting the workpieces to move smoothly through theoverall process. Each cell will now be described in turn.

In the initial cell, that is, staging cell 20, the skins and stringersare received and prepared for assembly. See block 10 of FIG. 1 and FIGS.3A-3D. In the staging cell 20, the skin planks 19 may arrive on astaging cart 42, while the stringers 21 may arrive on a staging cart 40.The skin planks 19 may be loaded onto an automated material handlingsystem, hereinafter described as an overhead positioning system, e.g., amonorail system (not shown), that engages the skin planks and carriesthe skin planks to successive cells in an automated manner. As shown,the staging cart 42 may include one or more cutouts that permit theautomated material handling system to access and engage the skin planks.The stringers may be moved from the staging cart 40 to a reconfigurablesmart cart, two of which are shown at 44. In the illustrated embodiment,the reconfigurable stringer smart carts 44 are shown to be disposed ontracks to direct the reconfigurable stringer smart carts to the nextcell, that is, to the tacking cell 22. However, the reconfigurablestringer smart carts may be directed to the tacking cell 22 in othermanners. In one embodiment, for example, the reconfigurable stringersmart carts 44 may be an automatically guided vehicle (AGV) that isautomatically guided from the staging cell 20 to the tacking cell 22. Byutilizing a plurality of reconfigurable smart carts 44, one smart cartmay be being loaded in the staging cell 20 prior to being sent to thetacking cell 22, while another smart cart is being unloaded in thetacking cell prior to being returned to the staging cell. FIG. 4provides another illustration of a staging cell 20 and depicts thetracks 45 that direct the reconfigurable smart carts as well as aportion of the overhead positioning system 47.

The smart carts 44 may be reconfigurable, such as by including aplurality of positioning elements, e.g., gripper fingers, pogos, edgeindexes, end gates and the like, so as to be configured to receive andsecurely hold the stringers 21. In this regard, the positioning elementsmay be configured to maintain and hold the stringers 21 in a predefinedposition, such as in a near net position so as to reduce the movementrequired by robots in a subsequent cell to interact with the stringers.In this regard, the stringers 21 may be staged upon the reconfigurablesmart carts 44 so as to be in the correct orientation, that is, apredefined orientation, upon delivery to the tacking cell 22.

The skin planks 19 and the stringers 21 may then be moved to the tackingcell 22 via the overhead positioning system and the reconfigurable smartcart 44, respectively. Once received by the tacking cell 22, such as bymovement of the reconfigurable stringer smart cart 44 into the tackingcell and movement of the skin planks along the overhead positioningsystem into the tacking cell, the skin planks may be delivered by theoverhead positioning system to programmably reconfigurable tooling. Asreferenced herein, programmably reconfigurable tooling may be programmedso as to define a plurality of predefined positions, therebyaccommodating a variety of different workpieces that are desirably heldin different positions. The reconfigurable tooling may include pogos,edge indexes, inboard edge endgates and the like, which may bereconfigured in order to receive and securely hold the skin planks at apredefined position and orientation.

With reference to FIGS. 5 and 6, the reconfigurable tooling of thetacking cell 22 may include a plurality of pedestals 51. Each pedestal51 may include one or more pogos 53 that may be controllably extendedfor engaging a skin plank 19 and establishing a predefined contour. Asshown in FIG. 7, one or more the pedestals 51 may also include an edgeindex 61. The edge index 61 is vertically adjustable relative to thepedestal 51 and also includes an engagement member that may becontrollably extended outwardly from the pedestal with the engagementmember including finger clamps for engaging an edge of the skin plank 19during the tacking operation. The reconfigurable tooling of the tackingcell 22 of FIG. 5 also includes a pair of opposed endgates 55 that mayalso include one or more repositionable pogos or other gripper fingers57 for engaging the opposed ends of the skin plank 19 and forcooperating with the pogos or other gripper fingers 53 of the pedestals51 for maintaining the skin plank in a desired position. The stringers21 may then be picked from the reconfigurable stringer smart cart 44 byone or more robots 59, placed in a predefined location upon the skinplanks 19 as defined, for example, by a digital database, and tacked,such as with a plurality of tack elements, to the skin plank. See block12 of FIG. 1.

After having tacked the stringers 19 to the skin planks, the tackedplanks may be moved, such as by the overhead positioning system, e.g.,the monorail, following release by the programmably reconfigurabletooling of the tacking cell 24, to the riveting cell 26. See block 14 ofFIG. 1 and the riveting cell 26 of FIG. 8. In the illustratedembodiment, the riveting cell 26 includes three riveting lines such thatthree tacked planks may be simultaneously riveted within the rivetingcell at one time. Nonetheless, in an instance in which the rivetinglines are already in use or the riveting cell 26 is otherwiseunavailable, the stringers and skin planks may be temporarily stored inthe buffer zone 24 positioned upstream of the riveting cell. The bufferzone 24 may provide a staging area for the tacked planks prior toentering the riveting cell 26 and may also permit the overheadpositioning system, e.g., the monorail, to transition the tacked plankslaterally so as to be aligned with a respective riveting line.

Each riveting line may include programmably reconfigurable tooling forreceiving and engaging a tacked plank 26 a. The reconfigurable toolingmay include pogos, edge indexes, inboard edge endgates and the like,which may be reconfigured in order to receive and securely hold thetacked planks 26 a at a predefined position and orientation, such as bygripping the edges of a tacked plank. As shown in FIGS. 8 and 9, forexample, the reconfigurable tooling of each riveting line may include aplurality of inboard endgates 63 that may be controllably extended orretracted. Each inboard endgate may include a pair of finger clamps forengaging an edge of the tacked plank 26 a and for maintaining the tackedplank in a desired position. The reconfigurable tooling of each rivetingline may also include opposed endgates 65 for engaging opposed ends ofthe tacked plank 26 a. As described above, the opposed endgates mayinclude a plurality of pogos or other gripper fingers that areconfigured to be controllably extended and to engage the opposed ends ofthe tacked plank 26 a while the tacked plank is maintained in thedesired position. In this embodiment, one tacked plank 26 a may beengaged by the reconfigurable tooling of each riveting line andmaintained in a predefined position while a riveter 28, such as anO-frame riveter, moves along the tacked plank, such as by moving overthe tacked plank with the tacked plank extending through the openingdefined by the O-frame riveter so as to more permanently rivet thestringers to the skin plank. While the riveters 28 move along the tackedplank, the components of the reconfigurable tooling that engage thetacked plank 26 a, such as the inboard endgates, may be automaticallydisengaged from the tacked plank and moved out of the way of theriveter, thereby allowing that portion of the tacked plank to be rivetedwhile the tacked plank is held in position by the other components ofthe reconfigurable tooling. The components of the reconfigurable toolingmay then be automatically returned to position in engagement with thetacked plank 26 a once the riveter 28 has moved to a different position.

In the illustrated embodiment, each riveting line includes two O-frameriveters 28 in order to operate concurrently so as to more quicklyprocess the tacked planks 26 a. However, the riveting lines can includeany number of riveters and different types of riveters, such asdifferently shaped riveters, in other embodiments. In the riveting cell26, the riveters install a plurality of permanent fasteners and replacethe tack elements with permanent fasteners, e.g., rivets. Following thecompletion of the riveting, the monorail or other overhead positioningsystem may engage the riveted plank and the programmably reconfigurabletooling may correspondingly release the riveted plank. In this regard,FIG. 10A illustrates the engagement of a riveted plank 32 a by anoverhead positioning system to provide for movement through themanufacturing system.

As shown in more detail in FIG. 10B, the overhead positioning system ofthe embodiment depicted in FIG. 10A includes a plurality of vice jaws 50that engage the riveted plank 32 a and that are configured to move inconcert along the overhead positioning system, thereby transporting theriveted panel. As shown in FIG. 10B, the vice jaw 50 of one embodimentmay include a track member 52 for engaging and moving along the monorailor other track of an overhead positioning system, as well as a pair ofjaw member 54, 56 that may be adjustably positioned so as to snuglyreceive differently sized planks. Each jaw member 54, 56 may include oneor more, e.g., a pair of, clamp members 58 that are configured to beadjustably positioned inwardly or outwardly along a respective jawmember. The jaw members 54, 56 and the clamp members 58 may bepositioned so as to snugly receive the riveted plank 32 a between theclamp members carried by respective jaw member. Additionally, the vicejaw 50 may include one or more extendable members 60, such as pogos,configured to adjustably extend into the jaw and to engage or contact aside surface of a riveted plank 32 a so as to further secure the rivetedplank within the jaw. Although described herein in conjunction with theengagement and transport of a riveted plank 32 a, the vice jaws 50 ofthe overhead positioning system may be configured to engage otherworkpieces, such as skin planks, tacked planks, etc. Additionally, whileone embodiment of an overhead positioning system and its vice jaws 50 isillustrated in FIGS. 10A and 10B and described above, the overheadpositioning system may be differently configured in other embodiments.

The riveted planks may then be moved to the splicing cell 32. Althoughthe splicing cell 32 may have a single line, the splicing cell may alsoinclude multiple lines, such as two splicing lines as shown in theillustrated embodiment of FIGS. 11-13. As such, a riveted plank 32 a maybe moved by the monorail or other overhead positioning system into thesplicing cell 32. In the splicing cell 32, multiple riveted planks 32 amay be spliced together with splice stringers. As such, the splicingcell 32 may include a storage rack 67 for holding the riveted planks 32a prior to the splicing operation until a sufficient number of rivetedplanks have been delivered to the splicing cell to permit the rivetedplanks to be spliced together. As such, the overhead positioning systemmay deliver the riveted planks 32 a to the storage rack 67. The splicingcell 32 may also include one or more robots 69 that may engage theriveted planks 32 a that are held by the storage rack 67 and move theriveted planks into alignment with programmably reconfigurable toolingonce a sufficient number of riveted planks have been delivered to thesplicing cell. The reconfigurable tooling will hold the riveted plank 32a in the appropriate position during processing within the respectivesplicing cell line. As described above, the reconfigurable tooling mayinclude pogos, edge indexes, inboard edge endgates and the like, whichmay be reconfigured in order to receive and securely hold the rivetedplanks 32 a at a predefined position and orientation, such as bygripping the edges of a riveted plank. In this embodiment, two or moreriveted planks 32 a, such as the number of riveted planks that comprisea wing panel, may be engaged and indexed by the reconfigurable toolingof each splicing line and maintained in a predefined position.

In the embodiment illustrated in FIGS. 11-13, the programmablyreconfigurable tooling of the splicing cell 32 may include a pluralityof vertical columns 63. In one embodiment, the vertical columns 63 aremounted upon tracks so as to be controllably translated lengthwiserelative to the riveted plank 32 a. The vertical columns 63 may carryone or more pogos, edge indexes, inboard edge endgates or the like thatmay be controllably positioned in order to engage the edges of theriveted plank 32 a and to marinating the riveted plank in the desiredposition during the splicing operation. As described above inconjunction with other cells, the reconfigurable tooling of the splicingcell may also include opposed endgates for engaging opposed ends of theriveted plank 32 a. As described above, the opposed endgates may includea plurality of pogos or other gripper fingers that are configured to becontrollably extended and to engage the opposed ends of the rivetedplank 32 a while the riveted plank is maintained in the desiredposition.

In addition to receiving the riveted planks 32 a, the splicing cell 32also receives a plurality of splice stringers, such as a plurality ofpresealed splice stringers. For example the splicing cell 32 may receivea cart, such as a reconfigurable stringer smart cart 44, that carries aplurality of splice stringers to the splicing cell with the splicestringers positioned in a predefined orientation upon the cart. Asbefore, the reconfigurable stringer smart cart 44 may move along tracks45 or the reconfigurable stringer smart cart may be directed in anothermanner, such as by means of automated guidance. In one embodiment shownin FIG. 2, the reconfigurable stringer smart cart 44 may move into thesplicing cell 32 from the side of body cell 34, thereby moving in thereverse direction to the flow of the processed planks through thesystem. One or more robots 69 may then pick a respective splice stringerfrom the cart 44 and may position the splice stringer an appropriateposition relative to the riveted planks 32 a that are positionedrelative to one another by the programmably reconfigurable tooling. Thesplice stringers may then be installed, such as by being bolted to theriveted planks 32 a by the robots 69 to the riveted planks, therebyintegrating the riveted planks into a unitary wing panel. See block 16of FIG. 1. By way of example, FIGS. 11-13 illustrate a splice line of asplicing cell 32 with one or more robots 69 operating so as to attachsplice stringers to the riveted planks 32 a.

In an alternative embodiment, a riveted plank may be suspended from themonorail or other overhead positioning system in alignment with adesired position within the splicing cell 32, such as in alignment withthe programmably reconfigurable tooling. The splice stringer may becarried by a smart cart 44 and parked beneath the riveted plank. Theplank may then be lowered into alignment with the splice stringer, suchas by lowering the riveted plank from the monorail or other overheadpositioning system. The riveted plank and the splice stringer may thenbe held in position, such as by reconfigurable tooling and/or a robot.After utilizing a robot to trace the edge of the riveted plank and thesplice stringers so as to identify their relative location, a bolter,such as a C-frame bolter, may tack the splice stringer and the rivetedplank together. As opposed to tracing the edge of the riveted plank andthe splice stringer so as to determine their relative locations, thelocation of a prior splice stringer may be utilized in order toappropriately locate the next splice stringer with respect to theriveted planks.

In another embodiment, the splice stringers may be delivered by a smartcart 44 to the splicing cell 32 and the riveted planks may be deliveredby the monorail or other overhead positioning system to the programmablyreconfigurable tooling which is configured engage one or more rivetedplanks and to hold the riveted plank(s) in a predefined position. Arobot may then engage a splice stringer and place the splice stringerrelative to the riveted plank. A second robot may then install afastener so as to fasten the splice stringer to the riveted plank(s).These two robots may then move in concert so as to install thefasteners. Other robots may move ahead of the robots that are installingthe fasteners in order to determine relative location of the splicestringer with respect to the riveted plank(s) and to reposition thesplice stringer as desired. This process may be repeated for each splicestringer that is attached to the riveted plank(s).

After being appropriately spliced, the spliced panel 34 a may be movedto a side of body cell 34 as shown in block 18 of FIG. 1 and in FIGS. 14and 15. The side of body cell 34 may also include one or more lines. Inan instance in which the side of body cell 34 includes a plurality oflines, multiple spliced panels 34 a may be processed at one time witheach line operating on a respective spliced panel. In the side of bodycell 34, the spliced panel 34 a may be delivered by a monorail or otheroverhead positioning system to a fixture or other tooling that maintainsthe spliced panel in a predefined position and orientation. The side ofbody (SoB) chord may then be installed by a robot and one or more paddlefittings may also be installed by a robot along with any required shimsto as to complete the assembly of the wing panel. In this regard, thefixture or other tooling may cause the desired contour to be provided tothe inboard end of the spliced panel with the side of body chord thenbeing installed at the inboard end of the spliced panel 34 a. In oneembodiment, one or more robots install the side of body chord and anyrequired paddle fittings with a plurality of bolts that engage theproperly contoured spliced panel 34 a.

With reference to the embodiment of FIGS. 14 and 15, the side of bodycell 34 may also include programmably reconfigurable tooling to hold thespliced panel 34 a in a desired position. In this regard, thereconfigurable tooling of the side of body cell 34 may include one ormore edge clamps 71 that may be adjustably positioned relative to thespliced panel 34 a, such as by moving inwardly or outwardly along floormounted rails and/or upwardly or downwardly along correspondingpedestals, so as to engage opposed edges of the spliced panel. Thereconfigurable tooling of the side of body cell 34 may also include oneor more endgates 73 for engaging an end of the spliced panel 34 a. Asdescribed above, the endgate may include a plurality of pogos or othergripper fingers that are configured to be controllably extended and toengage the end of the spliced panel 34 a while the spliced panel ismaintained in the desired position, thereby providing contour to thespliced panel during attachment of the side of body chord, such as tothe inboard end of the spliced panel.

The resulting wing panel may then exit the side of body cell 34 and beassembled with another wing panel, such as by assembling upper and lowerwing panels, so as to form a wing box. By automating the assemblyprocess and by utilizing operationally separate cells for performingdistinct manufacturing operations, the system and method of oneembodiment may manufacture wing panels and, in turn, wing boxes morerapidly and more efficiently.
